MARINE MOTOR.

Specification of Letters Patent.

Patented Jan. 4, 1916.

Application filed June 20, 1914. Serial No. 846,335.

To all 001mm if m (13 concern Be it known that I, LEWIS A. Douonnn'ry, acitizen of the United States, residing at Elkhart, in the county ofElkhart and State of Indiana, have invented certain new and usefulImprovements in Marine Motors, of which the following is aspecification.

This invention relates to improvements in marine motors.

The main objects of this invention are: First. to provide an improvedmarine motor adapted as an attachment for row boats, sail Second, toprovlde an improved marine motor whlch 1s readily-atboats and the like.

tached to a row boat, sail boat or the like, and which is adjustable toswing the propeller out of the water or to inoperative position and alsoto permit the propeller to pass obstructions. Third, to provide animproved structure having these advantages which is comparatively simpleand durable in structure and convenient to use.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a detail side elevation of my improved marine motor attachedto a boat, the boat being partially in longitudinal sections to bettershow the arrangement of parts, the arm 19 being indicated in itscollapsed position by dotted lines.- Fig. 11 is a detail view with themotor supported in its inoperative position, the boat being shown inlongitudinal section. Fig. III'is a detail horizontal section on a linecorre-- spending to the broken line 33 of Fig. I. Fig. IV is an enlargeddetail partially in vertical section on a line corresponding to line 4-fof Fig. III. Fig. Vis an enlarged detail section on a line correspondingto line 55 of Fig. 1, showing details of the mount-= ing for the enginein the supporting basket. Fig. VI is a sectional view of the propellersupport taken on a line corresponding to line 6-6 of Fig. II. Fig. VIIis an enlarged detail view of the tiller lock taken on a linecorresponding to line 7-7 of Fig. VIII.-

Fig. VIII is a detail transverse section showing details of the tillerlock taken on a line corresponding to line 8-8 of Fig. I. Fig. IXas adetail perspective view of a modified form of tiller lock. Fig..X is adetail sect1on of a modified form" of engine supportmg ournals. Fig. XIis a detail side View of the link 28.

In the drawing similar reference characters refer to similar partsthroughout the several vlews, and the sectional views are taken lookinginthe direction of the little arrows at the ends of the section lines.

Referring to the drawing, Fig. I is a side View of a boat to which myimproved motor I mechanism is secured as by means of the bracket 2,which is provided with a clamping screw 3 arranged through an arm 4 onthe brackets The bracketis provided with a pair of upwardly projectingarms 5 havin bushing-like bearings 6 for the journals of the cylinder 8.The journals are integral wlth the arms 9 projecting laterally from thesides of the cvlinder 8. These arms are so disposed that the journalsproper 7 are alined with the horizontal center of the cylinder. Thecrank case 12 is bolted to.the outer end of the cylinder as iswell-known practice.

The journals 7 are tapered and the bearmgs 6 are tapered to receive themso that the parts can be nicely adjusted. The arms 5 of the brackets aresplit and the bushinglike bearings are threaded therein for adjustment,clamping bolts 13 being provided for claimping the bearings in theiradjusted positions.

The crank shaft 14 has a fly wheel 15 on,

shoe 21which extends below and to the rear of the propeller 20. On theupper end of the housing 19 is a sleeve 22, the sleeve being split at 23and provided with a clamping screw 24 by means of which the sleeve .is

clamped upon the housing so as to turn ment of the sleeve independent ofthe 001- I lar. On the lower end of the supporting bracket or frame arerearwardly projecting arms 27, the arms being curved or segmental inform. A support comprlsing a pair of links 28 being pivoted to thecollar 26 at 30', while the link 29 is pivoted to the adjustable slidemember 31 on the arms 27 by thescrews 32 which also secure the slidemember, in its adjusted positions. The links are pivotally connected toeach other by the pivot The links are preferaby channel-shaped in crosssection so one closes into the other as 'shown in Fig. III. Frictionsprings 34 a re interposed between the links for applying frlctionthereto so that the motor is relieved from shock as it is thrown to itsinoperative position or as it swings to permit the propeller to passover an obstructlon or returns to its operative position. The link 29 1sprovided with a pin 35 which coaots wlth a segment shaped notch 36 onthe link 28 which prevents the links collapsing when extended. The pivot33 of the links when extended swings past a plane extending through thepivots 30 and 32 so that the links constitute a toggle lock and thelinksdo not tend to collapse and the propeller is supported in its raisedposition. A chain 37 is connected to the links for breaking the toggle.The clamp member 31 is slidable upon the arm 27 so that adjustment maybe had at this point. For locking the propeller in its vertical positionI provide a catch 38 which is bifurcated and pivoted on the collar 22 atthe points 39 and the arms of which are adapted'to engage the screws 32.The hand lever 40 is pivoted at 41- in convenient position to be reachedby. the operator, The lever is connected by the link; 41 to the catch.See Fig. I. clamped upon the sleeve 22, has a section 43 pivoted at 45and provided with a hand piece 44 so that the oscillating movement ofthe motor on its supporting journals does.

not interfere with the operation of the tiller. The rudder 46 is carriedby the rod 47, the lower end of which is supported by the shoe 21 andthe upper end ofv which is secured by the sleeve 48 to the arm 49projecting from the rear end of the tiller. The arm 49 is connected tothe tiller by the bolt 50 and to the sleeve 48 by the clamp 51 providedwith a clamping bolt 52. The sleeve is clamped to the upper end of therod 47 by the clamping bolt 53. This permits of the removal of therudder and when removed The tiller 42, which is messes 1 the arm 49isswungdown against the sleeve 22, as shown by dotted lines in Fig. 1,in which position it does not interfere with the normal operation of themotor, the propeller itself being used as the steering means. If it isdesired to use only the rudder as a steering means the clamp 51 .isloosened so that it serves as a bearing and cables, not shown, areattached to the cross arm 61 on'the sleeve 48. I preferably, however,use the rudder as an addition to the propeller steering means. 1 i

28 and 29 is provided, the hnk It is sometimes desirzible to lock thetiller in a central position and to accomplish this I provide the tillerwithajlock 54 which is secured in its adjusted position by means of theset screw 56 arranged ina longitudinal slot 57 in the tiller 42 tosecure the lock in its adjusted position, see FigQjVIli. The

lock is adapted to engage the notch-like keeper 58 in the cylinderflan'e,xsee VII. stop pm 59 assists in: ooatimg'v the lock in itsengaging and disengaging posiions.

When it is desired to adjust the lock 54 the set screw 56 Isloosene'dand the lock 'pushed longitudinally to or from engagingjournals 10 are screwed into the arms 9 instead of being integraltherewith as shown in the detail in Fig. V and the bearings 6 aresecured in their adjusted position by the lock nuts .6?

.In the modification shown in Fig. TX, I provide a simple screw 60' forlocking the tiller in a fixed position.

With the parts arranged as I have illustrated and described the motormay be quickly attached to or removed from a boat, such as a row boat ora sailboat. When using in shallow water or water in which there are logsor other debris the catch 38 is disengaged-so as to allow the propellerto swing as its shoe passesover an object. The friction springs preventshocks as the motor swings, on its journals. When desired, the propellermaybeswung out of the water and is automatically locked in its elevatedposition by means of the support described. The joint of the support isbroken to release the same by a pull on the chain 37. The rudder is alsoconvenient to operate and the combined action of the propeller andrudderare secured. t v

.5 I have not attempted to maintain the proper proportions of the partsin the accompanying. drawing as they are only intended to beillustrative.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
